CV Technology Explosion Rupture Panels allow the dangerous level of pressure generated from a dust deflagration to safely vent form the vessel being protected, eliminating breach and other pressure related failures. Each explosion panel is precisely designed to burst at a predetermined pressure to maintain structural integrity of the protected equipment by reducing the pressure produced to a tolerable level.
Explosion panels offer a passive and economical means of explosion mitigation. As opposed to other mitigation technologies, explosion panels feature a simple installation, quick replacement, and a long service life.
CV Technology offers a variety of different types of explosion vents based upon each specific process need. All of the CV Technology explosion panels comply with NFPA 68: Standard on Explosion Protection by Deflagration Venting, 2007 Edition. In addition, explosion panels can be equipped with accessories like:
- Burst indicators
- Specialty gaskets
The Interceptor®-HRD™ Explosion Suppression System is designed to provide an active method to protect process system equipment from a dust explosion hazard. The principle of operation for the Interceptor®- HRD™ system is detection of the pressure rise during the initial stage of an explosion, followed by fast injection and homogeneous distribution of an extinguishing agent into the protected vessel. The chemical suppression system consists of a controller, pressure or optical detectors, and the high rate discharge (HRD) bottles.
As a deflagration develops, the pressure inside the vessel will begin to build rapidly. The DetEx Explosion Pressure Detector will detect the rate of pressure rise over a certain time period and activate the High Rate Discharge bottles. Once activated, the HRD bottles will disperse suppressant into the protected vessel inhibiting the explosion from further developing, thus reducing the pressure and preventing any vessel breach.
In many process systems, it’s not enough to only protect the equipment where a dust deflagration is initiated – the interconnecting pipes and ducts through which vessels are linked must also be considered.
These interconnections can act as pathways for a dust deflagration and can lead to an increase in combustion strength and speed. This is because a propagating deflagration increases in turbulence while traveling down a constricted pipe or duct creating pressure piling and flame jet ignition in the conjoined equipment. The end result is a deflagration so powerful and unpredictable that conventional protection systems become inadequate and interconnected vessels and surrounding areas are left unguarded. The solution is to use one of CV Technology’s Explosion Isolation Technologies to stop a deflagration from propagating down its path to destruction.
